Subject: Recent changes to ALSA for power saving
Date: Tue, 26 May 2009 23:18:17 +0200
Hi all,
Luke and I have just pushed a one-line change to 9.10's
/etc/modprobe.d/alsa-base.conf that enables HDA controllers to power
down their amps after ten idle seconds. This change anticipates the
larger power-savings objectives for 9.10.
We expect there will be regressions in the form of audible pops when
the AMPs power down (and/or up). If you experience this symptom in
9.10, please file a bug using "ubuntu-bug alsa-base". Be sure to
change the summary of the bug afterward to "[9.10 regression] HDA
power_save=10".
Thanks,
Dan

Also:
Prior to this change, during shutdown, amps gives noise when they power down.
